Fiber optic transceiver module BlueOptics AFBR-79EADZ-BO QSFP 150m

The BlueOptics AFBR-79EADZ-BO QSFP 150m is a 40GBASE-SR4 compatible fiber optic transceiver module designed for short-range, high-speed data transmission over multimode fiber. Constructed in a lightweight aluminium housing and weighing approximately 20 g, it uses an MPO/MTP connector and operates at 850 nm for both transmitter and receiver channels. The module follows MSA-compliant QSFP form-factor standards and supports Ethernet, Fibre Channel over Ethernet and SDH/SONET protocols up to 40 Gbit/s with a typical reach up to 150 metres on appropriate multimode fibre plants.

Advantages

The transceiver offers a compact aluminium design with low weight for easy installation in switches, routers and storage systems. It is manufactured to MSA specifications and undergoes compatibility testing for use in systems that support the original AFBR-79EADZ interface, providing a direct functional equivalent for 40G short-range links. Integrated digital diagnostics (DDM/DOM) enable remote monitoring of supply voltage, laser bias current, transmitted and received optical power and temperature when supported by host hardware. Use of established component suppliers aims to ensure long operational lifetime and stable performance in data centre and enterprise networks.

Suitable for

• 40 Gbps short-reach aggregation and spine links in data centres
• High-speed server and switch interconnects within racks or between adjacent racks (up to 150 m)
• Storage area network and SAN switch connections using multimode fibre
• High-bandwidth campus backbone segments and equipment upgrades where QSFP is supported

Key specifications

• Form factor: QSFP (Quad Small Form-factor Pluggable)
• Data rate: up to 40 Gbit/s
• Wavelength: 850 nm transmitter and receiver
• Connector: MPO/MTP
• Optical medium: Multimode fibre (MMF)
• Maximum typical reach: up to 150 metres (depending on fibre type and channel conditions)
• Housing: aluminium
• Weight: ~0.02 kg
• Digital Diagnostics Monitoring (DDM/DOM) support when enabled by host hardware

How to use

Install the BlueOptics AFBR-79EADZ-BO QSFP into a compatible QSFP port on your switch, router or storage device while the host is powered down or following the equipment vendor's hot-swap guidelines. Connect an MPO/MTP multimode patch cable to the transceiver and route the other end to the intended patch panel or mating transceiver. Ensure that the connected multimode fibre (OM3/OM4 as required) and cable assemblies meet the link budget for distances up to 150 metres. If the host platform supports DDM/DOM, enable and read diagnostics via the device management interface to monitor optical power, temperature and voltage parameters.

Recommendations

Maintain clean MPO/MTP connectors and use appropriate multimode fibre (OM3/OM4) patch cords to achieve the specified reach. Verify host compatibility and software support for third-party QSFP modules before deployment. For troubleshooting, check DDM/DOM values and confirm fibre polarity and connector seating. Replace or test with known-good patch cords and transceivers if link issues persist.
